Feasibility of hysteroscopic endometrial polypectomy using a new dual wavelengths laser system (DWLS): preliminary results of a pilot study

Purpose Currently, endometrial polyps may be successfully treated in an outpatient setting with 5 Fr mechanical and bipolar instruments. Our aim is to evaluate the benefits of minimally invasive techniques in hysteroscopy, focusing on the use of a new dual wavelengths laser system in the treatment of endometrial polyps in an outpatient setting. Methods Between September 2012 and December 2014, all consecutive patients of reproductive and menopausal age with ultrasound diagnosis of endometrial polyp with maximum diameter ≤2.5 cm were eligible to participate in a prospective study. They underwent a hysteroscopic procedure with excision of the polyp using a new dual wavelengths laser system. All procedures were performed on an outpatient basis without anesthesia. Results Laser polypectomy was successfully performed in 219 out of 225 (97.3%). Success of surgery was not influenced by the initial location of polyp. No main complications were reported during or immediately after the procedure. 6 and 12 months follow-up with ultrasound scan did not show any persistence or recurrence of the pathology. Conclusions Our preliminary findings seem to support the safety and the effectiveness of the laser hysteroscopic endometrial polypectomy. However, further studies are mandatory to validate its use in daily hysteroscopic practice.
